Closing arguments Thursday highlighted a stark contrast in the versions of the defense and of the prosecution.

More rebuttal witnesses for the prosecution took the stand Thursday morning. Hubers watched as prosecutors called a forensic psychiatrist to the stand.

The psychiatrist the prosecution called to the stand, and the psychiatrist the defense called to the stand both agreed Hubers has post-traumatic stress disorder, but the prosecution's witness said she had it before the shooting and it was not a result of the shooting.

Both psychiatrists also agreed Hubers is bipolar and had a problem with alcohol and prescription drugs, but the prosecution's witness said Hubers did not appear to be affected by the problem in the police interview just after the shooting.

"In order to say that somebody is manic, what we have to observe is that the person has persistent and abnormally elevated or expansive or euphoric or irritable mood, and that just isn't the case," forensic psychiatrist Dr. Douglas Mossman said.

Hubers’ attorney, David Mejia, acted out the account of the shooting the defense believes unfolded, using the table where the victim was shot to death. Mejia said it was a clear case of self-defense.

"Her statement was she reached for the gun, grabbed it, first shot to the head. We know the trajectory went in the hairline and in a slight downward way," Mejia said as he stood in the place where he said the victim would have been.

Mejia said Poston was standing and on the attack until the final of six shots.

"Bang, bang … pause, bleeding … bang, bang, bang, bang and down he went to the floor," Mejia said as he hit the podium.

But prosecutors have a very different version of what happened.

Commonwealth attorney Michelle Snodgrass went to testimony of their forensic experts, who said Poston was shot while he was sitting at the table.

"There is no other justification for six bullets, there is no justification for her comment after comment after comment about, ‘I knew he was just about dead and he was twitching so I thought I’d put him out of his misery,'" Snodgrass said repeating similar statements made by Hubers, "That is cold-blooded murder."
